- Fixes an issue where `read_from` would read fewer bytes than it was expected to.
- Addded incomplete guard to an annotation consume that could cause an error
  when the buffer did not have enough data.
- Fixed an issue where bytes read into a NBR were counted twice when determining
  if all data had been read. This probably wasn't an issue since `read_from`
  reads all of the data requested.
- Implements stream completion for non-blocking binary reader.
- Moves Expandable to the raw_reader module now that the binary raw reader is using it.
